A simple pendulum \((OA)\) of length \(l\) is suspended from a point \(O,\) and the bob (mass : \(m\)) is given a transverse velocity, \(u=\sqrt{4gl}\) at its lowest point. When the suspended wire makes an angle \(\theta\) with the vertical, the stress in the wire is \(S.\)
Which, of the following, shows the proper dependence of \(S\) as a function of \(\cos\theta?\)
